Abstract: 370,872. Change speed gearing. KITTILSEN, C., Lille Traag, near Porsgrund, Norway. Oct. 8, 1930, No. 30139. Convention date, July 28. Void [Published under Sect. 91 of the Acts]. Addition to 365,581. [Class 80 (ii).] In a development of the auxiliary rear-axle bevel two-speed gear of the parent Specification, the speed change is effected by sliding a sleeve such as b3 with a clutch head b<2>. In the arrangement of the Figure, the sleeve b<3> is in driving connection with the differential c and may engage alternatively clutch rings b, bl inside the hubs of wheels B, B<1> constantly driven from pinions A, A<1> fast on the cardan shaft d. In a modified arrangement, the clutch sleeve slides so as to connect the cardan shaft alternatively to an aligned pinion shaft or to a pinion sleeve on the latter. The driven bevel wheels are in this case both fast to the differential casing.

Title: Improvements in or relating to fittings for supporting electric lampholders
IPC: H01R33/00
Filed: 1931-11-04
Abstract: 394,969. Supporting electric-lamp holders. GENERAL ELECTRIC CO., Ltd. and QUANCE, F. G., Magnet House, Kingsway, London. Nov. 4, 1931, No. 30576. [Classes 39 (ii), 75 (iii), and 75 (iv).] An electric-lamp holder 13 is detachably connected with a tube 3 in a canopy &c. and through which the leads pass by means of cranked arms 15 on a ring 14, secured to the holder, engaging clips 7 carried by cranked arms 5 on a disc 1 secured to the tube. Each clip 7 comprises a truncated metal cone 9 and a washer 10, slidably mounted on a bolt 8 and pressed together by springs 12. The arms 15 have a knife edge 18 and a slot 19, bevelled at the inner end. To attach the holder, it is pushed towards the disc 1, the cones 9 acting on the ring 14 to centre it relatively to the disc. The holder is then turned to engage the knife edges 18 with the cones and moved down, while still being rotated to retain the knife edges in contact with the cones, until the knife edges enter annular recesses formed bv annular rounded shoulders 11 on the cones and washers. On rotating the holder, the knife edges force apart the cones and washers, the slots 19 engage the bolts 8 and the springs 12 force the cones and washers into the bevels so that the holder is clipped firmly in position but is resiliently supported. The holder may be adjusted by reversing the ring 14 or by screwing the bolts 8 in the arms 5, thereby also adjusting the springs. In a modification, the cones 9 are fixed and provided with hollow spring plungers sliding on the bolts. The holder may be rigidly secured in a lantern, the ring 14 being mounted on the top of the lantern.

Abstract: Compounds of the formula <FORM:1113885/C2/1> in which R1 signifies a hydrogen atom or an alkoxy radical with 1 to 6 carbon atoms and n is 1 or 2, and their acid addition salts, are produced by subjecting to acid hydrolysis a compound of the formula <FORM:1113885/C2/2> in which R2 signifies an alkyl (C1-C6) or aralkyl (C7-C12) radical, and, when an acid addition salt is required, reacting the resulting compound with an organic or inorganic acid.  Examples describe the production of nortropane from N - (ethoxycarbonyl) - nortropane, of granatanine from 9-(ethoxycarbonyl)-9-azabicyclo [3,3,1] nonane and of 6b -methoxy-nortropane from 6b  - methoxy - N - (ethoxycarbonyl)-nortropane. The three starting materials were prepared by reacting chloroformic acid ethyl ester with tropane, 9-methyl-9-azabicyclo [3,3,1] nonane, and 6b -methoxy-tropane respectively.

Abstract: 1487023 Heat exchanger MODINE MFG CO 22 July 1975 [20 Dec 1974] 30611/75 Heading F4S A heat exchanger comprises spaced pipes 12, Fig. 2, within a conduit 16. Liquid flows through the pipes 12 and gas is drawn through the conduit 16 by a fan 28. The flowing gas is diverted by baffles 20, 18 and 21 so as to pass through spaces between the pipes 12 and through outlet duct 26 as indicated by arrows 17, 22, 17. The pipes 12 have fins 13 and extend between headers 14, 15, Fig. 1. The baffle 20 is conical and is in two parts 30, 31 which are pivotable to the position shown in Fig. 3 where gas passes through the apparatus without passing through the spaces between the pipes 12. There may be additional baffles, Fig. 4 (not shown), whereby the gas can be arranged to flow in an undulating path through the spaces between the pipes 12. The liquid may be water and the gas air. The exchanger may be used (a) to heat air from a hot liquid, e.g. to heat a worker-occupied space in a factory, or (b) to heat a liquid from a furnace gas, thereby recovering heat from a furnace exhaust. Movement of the pivotable baffle parts controls the amount of heat recovered.

Abstract: 784,025. Fibre-board &c. containing glass filaments &c. HAWLEY PRODUCTS CO. Oct. 27, 1955, No. 30736/55. Class 96. Felted fibrous boards or articles are made from a slurry of hydratable fibres, e.g. of kraft, cotton linters, caroa, or rag, with cut bundles of glass rovings or filaments, individually coated with water-insoluble material which does not adhere to the cellulosic fibres, e.g. 5 to 25 per cent of a fusible polyester resin, e.g. ethylene glycol reacted with maleic and phthalic anhydrides, styrene or vinyl compounds &c. being added; 1 to 25 per cent of a binder, which can adhere to both the hydratable fibres and the coated filaments and which may be dispersed with an anionic wetting agent being added also, and cured after felting. A cationic melamineformaldehyde or urea-formaldehyde resin or lauryl pyridinium chloride, " cocoamine acetate " or alum may be added as a mordant for the hydratable fibres, and the glass rovings may be coated initially with a Werner complex and polyvinyl acetate so that the polyester resin adheres preferentially thereto. The glass filaments may be transparent, white, or coloured for decorative effects, and may be 0.5 to 1.5 microns in diameter. The binder may be a thermoplastic or thermosetting resin and may include starch, or loading substances, e.g. clay, to make them less sticky; also, resins used may be compounded with driers, e.g. lead and cobalt salts of carboxylic acids. Preforms thus made may be impregnated with additional quantities of a polyester resin, or dried articles may be lacquered or varnished.

Abstract: 645,474. Boundary layer control ; screw propellers. STALKER, E. A. Oct. 16, 1946, No. 30803. Convention date, Jan. 12. [Classes 4 and 114] The boundary layer is sucked from the surface of an aircraft by a blower driven by a windmilling propeller, the blades of which may be retracted into a position clear of the airstream. In the form shown in Figs. 1 and 4, the propeller 22 is carried by a shaft 24 to the rear of the wing 6, the blower 20 being driven through bevel gearing 36. The propeller blades 26 are operated by a rack 48 which engages toothed sectors 50, 52, the rack being moved by a hand pump 36 controlling the supply of liquid to a cylinder 38 in which moves a piston rod 42. In the case of a jet-propelled aircraft the propeller may be mounted at the tail of the jet nozzle, the blades 52 being retracted into recesses 54 at the end of the fuselage, as shown in Fig. 5. With such an arrangement the propeller may be coupled to the compressor-turbine unit at take off through a shaft 109, clutch 106, and gearing 110, 105, Fig. 7. Each blade is moved to and from its retracted position by an electric motor 72, shaft 74, bevel gearing 76, 78, screw and sleeve 82, 84, and a link 86. Pitch control is effected by hydraulic rams 88, 90, the movement of which causes sliding of a sleeve 94 and rotation of a shaft 96 through helical slots 97, the shaft 96 carrying a bevel pinion meshing with a second pinion 98 on the hub arm 58.
